Yea, having some options that do not confer an obvious mechanical advantage are still nice to have. If it has no effect as per game mechanics - no special rules (that of a weapon modification) are needed at all, IMHO. It still needs value and rarity (and obviously a description). It is not like eve...

5. Vox-operated (ranged weapons only, weapon can be operated with voice commands) Unfortunately, this would make no difference from the point of game's mechanic. However, such custom peculiarity (added to add flavour to the particular gun) may actually come as part of purchasing the "Trademark...

I'm not too concerned with the damage capability; just that I think a projectile sniper rifle should have AP. But why do you think it should have that in the first place? First of all - a boltgun (.75 caliber mass-reactive armour piercing shells that is) is AP 0. And that's not too supportive on gi...
